I run Irongeek.com
I have an interest in InfoSec education
I don’t know everything - I’m just a geek with time
on my hands
Sometimes my
presentations
are like this.

And sometimes
my presentations
are like this.
Mile wide, 2.5 feet deep
Feel free to ask questions at any time
There will be many long breaks to play with the
tools mentioned

Other names:
Scoping
Footprinting
Discovery
Recon
Cyberstalking
http://Irongeek.com
DNS, Whois and Domain Tools
Finding general Information about an
organization via the web
Anti-social networks
Google Hacking
Metadata
Other odds and ends
http://Irongeek.com
For Pen-testers and attackers:
Precursor to attack
Social Engineering
User names and passwords
Web vulnerabilities
Internal IT structure (software, servers, IP layout)
Spearphishing
For everyone else:
You want to keep attackers from finding this info
and using this against you.
http://Irongeek.com
All these techniques are legal
Sorry if I “drop someone’s docs” other than my own
Please don’t misuse this information
http://Irongeek.com
Enable the interface:
ifconfig eth0 up
Get an IP:
dhclient
Start up the GUI/WIMP:
startx

Who-do the voodoo that you do so well
http://Irongeek.com
Glue of the Internet
Think of it as a phone book of sorts
Maps names to IPs, and IPs to names
(and other odds and ends)
Organization information is also kept
http://Irongeek.com
Host name to IP lookup:
nslookup www.irongeek.com
Reverse lookup:
nslookup 208.97.169.250

Just a few record types cribbed from: http://en.wikipedia.org/wiki/List_of_DNS_record_types
Code
Number
Defining RFC
Description
Function
A
1
RFC 1035
address record
Returns a 32-bit IPv4 address,
most commonly used to map
hostnames to an IP address of
the host, but also used for
DNSBLs, storing subnet masks in
RFC 1101, etc.
28
RFC 3596
IPv6 address
record
Returns a 128-bit IPv6 address,
most commonly used to map
hostnames to an IP address of
the host.
MX
15
RFC 1035
mail exchange
record
Maps a domain name to a list of
mail exchange servers for that
domain
CNAME
5
RFC 1035
Canonical name
record
Alias of one name to another:
the DNS lookup will continue by
retrying the lookup with the
new name.
PTR
12
RFC 1035
pointer record
Pointer to a canonical name.
Unlike a CNAME, DNS processing
does NOT proceed, just the
name is returned. The most
common use is for
implementing reverse DNS
lookups, but other uses include
such things as DNS-SD.
AXFR
252
RFC 1035
Full Zone
Transfer
Transfer entire zone file from
the master name server to
secondary name servers.
